The drawback of renewable technologies is the lack of coupling with energy demand, to reduce these drawbacks is by applying hydrogen as an energy vector. Hydrogen obtained from renewable energy sources could be stored and used when required, directly or in fuel cells. This work focuses on determining the hydrogen potential that can be obtained using photovoltaic plants in urban areas. In the city of Cuenca, with the renewal of the public transport vehicle fleet, it was reduced to 475 units, which emit 112 tons of CO2 and burn 11,175 gallons of diesel per day. The analysis determines the photovoltaic energy that is produced by implementing photovoltaic panels in the Historic Center of Cuenca, Ecuador. With this it is determined that the electrical energy produced is 5.5 times the demand of the study area. With the energy surplus, it was determined that energy would be available that would cover between 97% and 127% of the demand required to mobilize the total urban buses. There are advantages such as the reduction of emissions or the increase in the quality of life, but the economic and technological aspects could be barriers to the implementation of these in the medium or short term.

“…Considering that the amount of energy required to mobilize an electric bus has been estimated to be 0.81 km/kWh [4] to 0.93 km/kWh [42], then, as before an average performance of 0.865 km/kWh has been considered. So, the possible distance to be travelled by electric bus can be estimated with the available power surpluses: Distance = available electric power * performance bus (9) Distance = 38, 830, 630.55km…”

Considering the total distance demanded of 32,610,650 km, it is possible to establish that 463% of the route of the urban vehicle fleet can be covered.…”

A main restriction of renewables from intermittent sources is the mismatch between energy resource availability and energy requirements, especially when extensive power plants are producing at their highest potential causing huge energy surpluses. In these cases, excess power must be stored or curtailed. One alternative is increasing urban solar potential which could be integrated to feed electric buses directly or alternatively through hydrogen (H2) as an energy vector. H2 from renewable electricity can be stored and used directly or through fuel cells. This study aims to determine the H2 capability that could be achieved when integrating large-scale photovoltaic (PV) generation in urban areas. This analysis was carried out by determining the PV energy potentially generated by installing PV in Cuenca City downtown (Ecuador). Cuenca is in the process of adopting renewal of the public transport vehicle fleet, introducing a new model with an electric tram main network combined with “clean type buses”. The conventional diesel urban transport could be replaced, establishing a required vehicle fleet of 475 buses spread over 29 routes, emitting 112 tons of CO2 and burning 11,175 gallons of diesel daily. Between the main findings, we concluded that the electricity that could be produced in the total roof area exceeds the actual demand in the study area by 5.5 times. Taking into account the energy surplus, it was determined that the available PV power will cover from 97% to 127% of the total demand necessary to mobilize the city bus fleet. The novelty of this work is the proposal of a combined methodology to find the potential to feed urban transport with urban solar power in cities, close to the equatorial line.
